Preliminary experiments of LVAssrA-tag
In order to prove that our toolkit is efficient to switch two interest genes’ expression from GFP to RFP and to eliminate the accumulation of expressed protein to interfere our measurement. We fused a degradation tag at the amino terminal of our reporter. And we used plac from the Rgistery (BBa_J04500) to characterize the degradation tag LVAssrA. We use IPTG with final concentration of 1mM to induce the GFP-LVAssrAtag and measure the relative fluorescence through plate reader with Excitation light 495nm.
